Ronquera - Objective Automatic Assessment of the Level of Dysphonia

The severity of dysphonia is traditionally assessed by perceptual means. Objective (optical, electrical, acoustical) measures have been developed to compensate the subjectivity of perceptual assessment. However, these measures have failed to be sensitive (reflect changes of the perceptual trait), specific (reflect changes only of the intended perceptual trait), and consistent (with similar results across different studies) enough to be adopted in clinical practice. The project "Ronquera" (span. "hoarseness"), supported by the Humboldt Foundation, addresses these problems (see also the homepage of Carlos Ferrer-Riesgo).

Former Project (2015)


The Kassel stutter therapy is applying a fluency shaping technique to help stutterers speak fluently. To offer improved training possibilities for the clients, we are developing algorithms to automatically analyse whether speech exercises are being performed correctly in the ASSIST project (Automatic Speech analysis for an assistance system for Systematically Increasing the contextual and interactional requirements in Stuttering Therapy).
